Peter Chrysologus was Bishop of Ravenna, the capital of the empire in the West, from about 433 until his death. After hearing oratory of his first homily as bishop, Roman Empress Galla Placidia supposedly gave him the surname Chrysologus, meaning "golden-worded." He was declared a Doctor of the Church by Pope Benedict XIII in 1729.
Born at Imola, 406; died there, 450. His biography, first written by Agnellus in the ninth century, gives but scanty information about him. He was baptised, educated, and ordained deacon by Cornelius, Bishop of Imola, and was elevated to the Bishopric of Ravenna in 433.
At the time there were abuses and vestiges of paganism evident in his diocese, and these he was determined to battle and overcome. His principal weapon was the short sermon, and many of them have come down to us. They do not contain great originality of thought. They are, however, full of moral applications, sound in doctrine and historically significant in that they reveal Christian life in fifth-century Ravenna. So authentic were the contents of his sermons that, some 13 centuries later, he was declared a doctor of the Church by Pope Benedict XIII. He who had earnestly sought to teach and motivate his own flock was recognized as a teacher of the universal Church.
In addition to his zeal in the exercise of his office, Peter Chrysologus was distinguished by a fierce loyalty to the Church, not only in its teaching, but in its authority as well. He looked upon learning not as a mere opportunity but as an obligation for all, both as a development of God-given faculties and as a solid support for the worship of God.
Some time before his death, St. Peter returned to Imola, his birthplace, where he died around A.D. 450.
As probably one of the most important parts of the material part of his legacy, we can find many Jesuit schools and general educational institutions worldwide. In the United States alone there are 28 Jesuit colleges and universities, and more than 50 secondary schools.
